I have looked closely at the sound.cfg file and the .air file and can find no reference to the type of sound allocated to any given aircraft by the sim/ai sound engine.

If I can find out this information,I would assume it would be possible to have the 5 different sounding jets, like Conways, JT series, GE turbos, Speys etc which could then be matched to the aircraft as I already have them recorded.

I tried the obvious by putting the .air file from a C172 onto a 737, hoping to hear the Cessna ai sound, but alas, the sim still played the small jet ai sound, so I carnt see the reference being in the .air file.

Thx Paavo for the reply. I guess it is buried in the aircraft.cfg file somewhere, was just hoping someone might know just which entry the ai sound engine looks at in that file. I think we can safely discount the .air file tho.
